This works similar to the
schematic in AN AVR400,
but constant voltage on AIN1
and variable loading speed of
the capacitor at AIN0.

Switch one I/O to Output Low, the others
to Input, to drain the capacitor. Then switch
the output to High and measure the time
until the Analog comparator triggers.

The Pololu PRG03A programmer delivers
5 V signals, so we need voltage dividers.
They could go into an adapter cable later,
but this needs Vcc. Unsure wether Vcc
has to be 5V.
